Yes, I noticed the resize issue too but did not want to go over the allotted dev time.
To be honest, almost all the code is from the example project or generated. I checked each line of code but was happy with the implementation and only tweaked some of the values manually to make the physics feel right. I'm considering typing more of the code manually next time, the hosted LLM feels like an unfair advantage.
Regarding the high score: I managed only 351, but my girlfriend got to 974 m!
